AC Milan boss Max Allegri believes there are more threats to their title chances than just second-placed Napoli.
Allegri insists there's still a long way to go in the race for the Scudetto.
He said: "I don't know if it will be like this at the end.
"Napoli are doing important things and, at the moment, they appear to be the most dangerous opponents.
"I think that they will last until the end, but there are other teams in pursuit of the Scudetto and they will give us a hard time until the end of the season. There are five or six title contenders."
